Which energy sublevel is being filled by the elements Ce to Lu?
4F
Elements in which the d-sublevel is being filled have the properties of?
metals
How would you justify the presence of 18 elements in the fifth of period of periodic table?
In the fifth period of the periodic table, the atoms of the elements in the first two groups are adding 1 and 2 electrons, respectively, to their highest energy 5s sublevel. Starting in group 3/IIIB and going through group 12/IIB, the atoms of those elements are adding electrons to their highest energy 4d sublevel. Since the d sublevel can contain a maxium of 10 electrons, there are 10 elements whose atoms are filling the 4d sublevel. Once the 4d sublevel is filled, the next higher energy sublevel is the 5p sublevel. Starting with the group 13/IIIA elements, the 5p sublevel is being filled. Since a p sublevel can contain a maximum of 6 electrons, there are six elements whose atoms are filling the 5p sublevel. 5s sublevel filling: 2 elements 4d sublevel filling: 10 elements 5p sublevel filling: 6 elements --------------------------------------- Total: 18 elements For a printable periodic table that includes electron configurations, go to the following link: http://www.nist.gov/pml/data/periodic.cfm
Why is copper a transition metal as it have completely filled d sub-shell?
An electron moves from the 4s sublevel to produce a completely filled 3d sublevel. A completely filled sublevel is more stable. Just because it has a filled d sublevel doesn't prevent it from being a transition metal. It has variable valence (1+ and 2+).
When do D orbitals start gettin filled?
D orbitals begin being filled with electrons after the orbital found in the 4s sublevel is filled.

Why aren't there any p-block elements in the first period of the periodic table?
Because in the first period, only the first energy level is being filled with electrons, which can take only a maximum of 2 electrons in the s sublevel. The electron configuration of hydrogen is 1s1 and helium is 1s2. There is no p sublevel in the first energy level.
The Aufbau principle states that an electron?
The Aufbau principle states that electrons must be added to elements and ions in a VERY specific order with the lowest energy level being filled first and the highest last. This is where the Aufbau triangle comes in. It shows the order in which the energy levels must be filled.

D orbitals begin being filled with electrons after the orbital found in the 4s sublevel is filled.
Which energy sublevel is being filled by the element K to Ca?
4s. Both K and Ca are s block and they are both in the 4th period. So in K, you have 4s1 and in Ca you have 4s2
elements in which the s and p arbitals in the outer shell are entirely filled are?
These elements, known as the alkali metals (group 1A) and alkaline earth metals (group 2A), are those in which the outer-shell s orbitals are being filled. On the right is a block of six columns. These are the elements in which the outermost p orbitals are being filled.
What is the explanation for the p block periodic table?
The p-block is just a part of the periodic table, from Group13 to Group 18. (13,14,15,16,17,18)The periodic table has four blocks: s-block, d-block, p-block, and f-block.I will add a link so you can visualize this...The p-block is called like that because the p sublevel of its atoms is being filled with electrons.P.S. The s sublevel fills completely with 2electrons.The p sublevel fills completely with 6electrons.The d sublevel fills completely with 10electrons.The f sublevel fills completely with 14electrons.
What do the rows in a periodic table group together?
The rows on the periodic table correspond to the highest energy level being filled by the elements in that row (period). For example, in period 3, the elements are filling their valence shell in the 3rd energy level from left to right across the period, from 3s1 in sodium to 3s23p6 in argon.
Elements belong in upper ionization energy?
All of the elements on the top half of the periodic table belong in upperionizationenergy because the trend is top to bottom. Top being lowest and getting bigger as it goes down.------------------------------------------------------* In a group: the ionization energy decrease from the lighter elements to heavier elements.* In a period: the ionization energy increase from the left elements to the elements of the right.* When the atomic radius decrease the ionization energy increase.
